Like reference characters refer to like parts in the different figures.

Referring first to Figs. 1 and 2 the machine consists of a base 5 having upright members 2,3, 6 and 5 on the upper end of which are attached cross members 6 and l. The front upright members 2 and 3 have slide ways 8 and 9 respectively, Fig. 3, in which is slidably mounted a reciprocable slide member I0.

The main slide member Ill has a projecting bracket H to which is attached a piston rod l2 which extends through one end of a hydraulic cylinder 13, said cylinder being mounted on the base I. The end of the piston rod I2 is screw threaded in order that nuts I land I5 can be used on opposite sides of the bracket H whereby the slide in may be adjusted in orderto insure the said slide moving to the correct upper position in relation to the rest of the machine.

The slide member It) also has slide ways l6 and i l in which is slidably mounted a slide member is said member having a projecting boss IS with a hole therein for the threaded end of a piston rod 20 which extends through one end of a cylinder 2!. ed on the rod 2!! so that they abut the top and bottom sides of the hub l9 respectively whereby the slide. member is is adjustably secured to the said piston rod. The cylinder 2|, Fig. 12, is shown to be a dash pot filled with fluid that flows from end to end through a passage 24. In order to control the downward movement of the slide 18 by the fluid in the cylinder 2i an adjustable needle valve 25 is placed in a passage 26, said passage forming the port through which the fluid enters the upper portion of the cylinder when the slide starts moving downwardly. By means of the needle valve 25 the passage 24 is more or less restricted whereby the rate of descent of the slide it is governed.

Extending 'rearwardly of the base I, Figs. 2 and 3, is an inclosed tank 21 which acts as a sump for the fluid used in the hydraulic system.

Mounted on the tank 21 is a driving motor 28 and a pump 29 said motor and pump being geared together by gears 30 and 3!. The gear 3| being mounted on the driving shaft, not shown, of the pump, said shaft also carrying a gear 32, Fig. 2, which drives a gear 33. The gear 33 is mounted on one end of a shaft 34 which is rotatably mounted in bearings 35 and 36 provided on a member 31, said member being mounted on and fastened tothe tank 2i. On the opposite end of the shaft 34 is a chain sprocket 38 the purpose of which will more clearly hereinafter appear.

Nuts 22 and 23 are screw thread--- Mounted on the front of the base I, Figs. 1, 2, 3 and 5, is a valve casing 39 in which is slidably mounted a piston type valve member 49 which has a circumferential groove 4! The valve casing 39 has an arm d2 in which is a bearing for a rod 43 on one end of which is fastened a valve actuating member 441 having a projection 45 that fits the groove ii. The valve actuating member 44 has a stop member 58 to limit the movement of the valve member 49 in one direction.

The rod 63 extends across the front of the machine through a bearing in a bracket 41, said bracket being suitably fastened to the. base I. A lever ii Figs. 1 and 5, non-rotatably fastened to the other end of the rod 43, carries a stud 49 upon which is rotatably mounted a link 59, the other end of said link being mounted upon a stud SI carried by a lever 52. The lever 52 is nonrotatably fastened to one end of a rotatable shaft 53 on the other end of which is non-rotatably mounted a foot treadle 54.

As shown in the drawings the foot treadle 54 is in its downward or operative position whereby the fluid under pressure from the pump 29 flows by the way of pipe 55 through the main valve 39 to the rest of the system. When the treadle 54 is depressed by the operators foot the valve member 49 is moved against the action of a spring 55, Fig. 20. As soon as the operator removes his foot from the treadle 54 the spring 56 will move the valve member it to the right as seen in Fig. 20 until it is stopped by the stop member 46 coming in contact with the top of the valve casing 39.

A reversing valve 571, mounted on the base I to the rear of the main slide I0, Figs. 2, 3 and 20, is provided with two pairs of arms 53 and 59 between each pair of which is mounted one of the oscillating members 55%) and 6| respectively. The members 69 and ii! are mounted on shafts 62 and 63 which are rotatably mounted in bearings provided by the arms 53 and 59. The valve 51 has a central opening [54, Fig. 20, in which is slidably mounted a piston valve 65 having extensions 66 and 57! which are contacted by the members 653 and GI. A pipe 68 connects the main valve 39 with the reversing valve 57 and a pipe 69 connects the said reversing valve with main slide actuating cylinder I 3.

As shown in the drawings the main slide I0 is in its lowermost position at which time an adjustable abutment member I9, on the rear of the main slide, is in contact with the, oscillatable member 63 causing said member to rock about its fulcrum 92, and move the piston 65, toward the left, Fig. 2 or upwardly to the position shown in Fig. 20, so that fluid under pressure is being admitted at the bottom of the cylinder I3.

Attached to the upper end of the slide Ill is a pair of brackets HI and I2 upon which are mounted members 13 and M respectively, said members forming a pair of picker fingers for removing labels from a source of supply.

The main slide It has mounted thereon, Figs. 1, 3 and 4, a latch member '25, fulcrumed at '16 in a slot ll, having a contact member 78. The latch 15 is held in latching position by a spring I9.

The slide 58, mounted in ways It and IT on the main slide I9, is slotted at to receive the latch member E5 when both slides are in their lowermost position so that when the main slide It moves upwardly the second slide it moves with it up to a predetermined position. The second slide I 3 is released from the main slide I 9 by means of a cam 8i adjustably fastened to the side frame 3 by means of screws 82.

A pair of arms 83 and 84, Figs. 1, 2 and 9, are fulcrumed at 85 and 86 on studs fastened in the second slide I8. On the upper end of each of the arms 83 and 84 is mounted a wiper pad 81 and 88 of resilient material so that when they Wipe a label over a bottle they will press the said label firmly on the bottle without tearing or wrinkling it. Part way down on the wiper arm and below the fulcrum points 85 and 85 are rotatably mounted cam rollers 89 and 99. The lower end of each of the arms 53 and 84 is provided with a spring pressed detent 9i having a projecting portion 92, Fig. 9, which fits into a depression 93 formed in a guide member 94. The guide member 94, Figs. 2 and 9, is suitably fastened on the front of the second slide I8. There is a guide member for each of the arms 83 and 84 so that when the arms are in wiping position as shown in Fig. 9 the detent 9! will hold the said arms thus until moved to the position shown in Fig. l.

A bottle stand 95, suitably mounted on the base I, Figs. 1 and 2, has a pair of double cams 96 and 9'1 mounted on the front thereof, the cam 96 causing the arms 83 and 84 to assume the position shown in Fig. 1 when the rolls 89 and 96 contact the cam surfaces 91 and 98 respectively. The cam 9'! causes the said arms to assume the position shown in Fig. 9 when the rolls 89 and 99 contact the cam surfaces 99 and I00. A suitably shaped member Ifil is adjustably mounted in the upper end of the stand whereby bottles A of various sizes and shapes can be suitably located in relation to the other parts of the machine.

The base I has an aperture I92, Figs. 3, 6, '7 and 11, on one edge of which is fastened a depending bracket I03. The bracket has ways I04 and I05 in which is slidably mounted a member I06, the said member also having a pair of bearing members I01 and I98 in which is rotatably mounted a short shaft 39. The member I06 has an extending boss I It in which is a hole I II having a spring H2 and plunger H3. The plunger H3 has an enlarged end I114 which abuts an adjustable stop II5, said stop being screw threaded in an L shaped, downwardly extending projection H6. The stop I55 governs the tension on the spring II2 when it is compressed by the slide I 06 in its latched position. In order to govern the height to which the spring I I 2 moves the slide I536, after it'is released from the latch, a screw threaded member IIii', Fig. l, is fastened to said slide. The member I I0 extends through and below the projection I I6 and has an adjustable abutment I Ill, in the form of a nut, which limits the upward movement of said slide I II] by coming in contact with the under surface of the projection Securely fastened to the rotatable shaft I99 is a lever arm II 'I having a projection I I8 on its hub II 9. On the upper end of the arm II! is fastened a member I20, Figs. 1, 6 and 7, which carries one or more strip or presser pads I2I, I22 and I23. The strip pads have projecting studs I2d, I25, I26 and i2! extending through suitable holes in the member I29. Springs I28, I29, I30 and I3! surround the studs between the member I29 and the strip pads IZI, 322 and I23 so that the said pads are resiliently spaced from said member. Cotter pins or other suitable means is provided to hold the said pads in attached relation to the member I29.

In front of the lever arm I i I is positioned a bracket I32, Figs. 6 and '7, having a hub portion ...cylinder I74. From the above it will be seen that movement of the piston rod III will cause the carriage I56 to be moved back and forth a distance I33 in which is no'n-rotatably mounted a stud =I34. -Rotatably mounted on the stud I34 is a latch member I35 having a downwardly extending .armI38 and a rearwardly extending portion I31 which .has an extension I38 at right angles to the rearwardly extending portion I3'I. As shown in Fig. 6 the. slide I96 is in its lowermost position at which time thearm I I1 is in a vertical position. 'Withthe said slide andarm in this position the arm I36, of the latch member I35, is in contact with the projection II8 of the lever arm II"I thereby holding the said arm and its slide I95 against the action of the spring II2.

Attached to the main slide In is a latch actuating member I39, Figs. 1, 3, 6 and 7, having an angular projection I49 in which is screw threaded an adjustable stop I4I which is held in adjusted "position by means of a check nut I42. -When the slide I9 moves upwardly as will be more clearly hereinafter explained the stop member I4I will contact with the extension I38 of the latch member I35 and rock the said latch member to the positionas shown in Fig. 7. Rocking the latch member I 35 will release the lever arm II! and allow the spring I I2 to raise the slide I95 to its upper position.

As the slide I8 descends an adjustable abut- 'mentmember I43, Figs. 3 and 8, on the rear of said slide will contact with a stud I44 provided on the lever arm Ill and cause the said arm and its slide I85 to move downwardly against the action of spring I I2. Inasmuch as the latch actuating member I39 is also attached to the slide I9, "the latch member I35 is released from its influence and returns to its natural position, Fig. 6, by gravity so that when the projection I I8 of the arm III passes by the latch I35 it will contact the said projection and prevent the spring IIZ from moving the said arm upwardly until the proper time on the next upward movement of the main slide I9.

7 A cylinder and piston unit I45, Figs. 1, 2, 3 and 20, is suitably mounted on av member I45 provided by the base I. A piston rod I41 extending through one end of the cylinder I48 has a tongue portion I49 on the end thereof carrying a pin I 59. A pair of rods I5I and I52 are loosely mounted on the pin I58 at one end while the other end of said rods are loosely mounted on a pin I53, Figs. 6, 7 and 8, fastened in the lever arm II'I. From 'the above description it will be apparent that movement of the piston rod I48 will cause the .arm II! to oscillate from the position of Fig. 6 to the position of Fig. '7 when fluid under pressure is admitted to the cylinder I48.

The cross members 8 and 'I have ways I54 and I 55 respectively, Fig. 1, in which is slidably mounted a carriage I56 having a pair of bearings I51 and I58 depending from the front end thereof and a depending member I59, Fig. 2, at the rear end. The depending member I59 has a stud I69 on which is slidably mounted one arm IBI, having an elongated slot I52, of a two armed lever I83 fulcrumed on a stud I54 that is carried by an arm I85 of a bracket I55 said bracket being suitably fastened to a cross member between the rear uprights 4 and 5.

The other arm IG'I, of the lever I53, Figs. 2 and -20, has an elongated slot I58 in which is slidably positioned a pin I69 fastened in an adjustable member I19. The member I70 is mounted on the screw threaded end of a piston rod Ill and is held position by means of .check nuts H2 and I13. Thepiston rod I'II extends through one endof-a as provided by the adjustment of the member I'IIJ on the piston rod I II. 115 A reversing valve I'I5, Figs. 1, 3, 10 and 20, is mounted on the member I49 which has an arm I I8 that carries a stud ITI. A two armed lever I18, rockably mounted on the stud I'I'I, one arm I19 of which is in contact with an actuating meme10 ber I89,v adjustably fastened on the rearof the main slide Ill. The other arm I8I'of the lever III? has a stud I82 which engages in a circumferential groove I83 of a valve plunger I84. The actuating member I89 has a recessed portion I85,&'.15 Fig. 10, and a projecting end portion I86. When the slide It moves upwardly the projecting end I86, of the actuating member I89, contacts with the end of the arm I18 rocking the lever I78 in an anti-clockwise direction which causes the valve .20 plunger I84 to be moved to the left. As the slide II] moves downwardly again the beveled portion I 8! contacts with the end of the arm I19 and rocks the lever H8 in a clockwise direction which moves the valve plunger I34 to the right as shown .25 in Fig. 10.

Referring now to Fig. 20 it will be seen that the reverse valve I is connected to the main valve 39 by means of a pipe I85 which enters the said reverse valve at port I85. The valve memi130 ber I84 is provided with reduced portions I81, I88 and I89 which are separated by full'size portions I99 and I9I while the full size end portions I92 and I93 form one end of the passage made by the reduced portions I8! and I89 re-g35 spectively. With the valve member in theouter position as shown in Fig. 20 fluid under pressure entering port I88 passes around the reduced portion I81 and out port I94 to passage I95. From the passage I95 is a port I95 through which the,.; fluid enters and flows around the reduced portion I89 and out of port I97 to pipe I98. Pipe I98 enters port I98 at one end of the cylinder I'M and the fluid under pressure normally maintains the piston and rod MI in the position as shown. A branch lead I99 from the pipe I98 conducts fluid under pressure to a port 299 in the cylinder I48 and maintains the piston and rod I41 in the position as shown.

The exhaust fluid from the cylinder I48 is out of port ZIJI to pipe 292 which enters a port 293 in the valve H5. The exhaust fluid flows around the reduced portion I88 to port 294, pipe 295 and back to the sump or supply tank 27. The-exhaust fluid from the cylinder I'M escapes out of port. 55

296, pipe 297 to port 209 in the valve I15 and" thence to port 294 and pipe 285 to the sump.

Referring now to Figs. 1 and 2 relative to the reciprocable slide I56 and its associated parts it will be noted that the bearings I5! and-I58,. have bearing surfaces 299, only the bearing sur-'' face of bearing I51 being shown, in which is rotatably mounted a shaft 2I9 that is held in said bearings by means of holding clips 2| I. By using holding clips to retain the transfer, roll shaft M9 in position, it is possible to quickly 5 and easily remove the roll 2 I4 from the machine for cleaning purposes. Collars M2 and 2I3 are secured to the shaft 2H] adjacent each of the bearings I5'I and I58 to prevent axial movement of the said shaft. A transfer roll 2 I4 of resilientmaterial is also fastened to the shaft 2I9.

Acam 2I5, fastened to the upper side of the slide I56, is contacted by a cam roll 2| 6 which is rotatably mounted on a stud 2i! fastened on -a lever 2I8 fulcrumed on a shaft-2H), Figs. -1 2 and 13. The shaft 219 is rotatably mounted in suitable bearings provided on a member 226. The member 220 is adjustably fastened to the crossmembers 6 and 1 thereby holding the upright members 2, 3, 4 and 5 in correct relation with each other.

A lever 22l, fastened to the shaft 2I9, has an open end slotted portion 222 which slidably fits a stud 223 carried by a projecting portion 224 of a vertically reciprocable label supply receptacle generally designated as 225. The label supply receptacle by and of itself forms no part of the present invention as they are old and well known in the art it being sufficient to say that the said receptacle is carried on a member 226 having guide ways 221 and 228 which are slidably mounted in vertical ways 229 and 236 provided by the cross member 226.

From the above description of the label box 225 and its connections it is seen that as the slide I56 moves to the left, Fig. 2, the roll 2I6 will ride along the surface of the cam 2I5 until it reaches the inclined portion. Upon starting down the inclined portion of the cam 2I5 the weight of the label receptacle 225 will cause the roll 2I6 to follow the cam closely by means of the levers H8 and 221 which are fastened to the shaft 2 I 9 and when the slide reverses its direction of movement the cam 215 causes the label receptacle to raise up to the position shown in Fig. 2. The cam M5 is adjustable on the slide I56 to govern the label receptacle in relation to the picker fingers 13 to insure that the labels are pressed on said fingers with the right tension.

In setting up the machine it is desirable to reciprocate the slide I56 without having the label receptacle 225 move downwardly each time and therefore a lever 255i is secured to the shaft 2I9 while a second lever 232 having a locking face 233 is fulcrumed at 234 on a stud 235 carried by an upright portion of the cross member 226. When the operator wishes to have the label receptacle remain stationary during reciprocation of the slide I56, he swings the lever 232 by means of the handle 236 in a clockwise direction whereupon the locking face 233 contacts with the end of the lever 23I which, being secured to the shaft 2I9, causes the roll 2I6 to be raised away from the cam 2I5 in which position it is locked until the operator again manually moves the lever 232 in an anticlockwise direction to allow the roll 2 I6 to again contact the cam H5. The lever 232 rests against a pin 231 when in inoperative position.

As thus far described the machine is capable of putting on either one or two labels, i. e. body and neck labels, at each cycle but in many cases it is desirable to put on a third label or foil entirely around the mouth end of the bottle. As indicated in Fig. 2 the label receptacle 225 is arranged to hold three stacks of labels or two stacks of labels and one stack of foils.

In order that the drawings may clearly illustrate the invention the foiling mechanism control cylinder is merely indicated in Fig. 1 while the mechanism in its entirety is shown in Figs. 14 to 19 inclusive. Brackets 238 and 239, fastened to uprights 2 and 3 respectively, have extensions 24!] and 2M. As both of the foil wiping or forming mechanisms are of substantially the same construction only one of them will be described in detail while their operations and mode of functioning will be described in conjunction with their actuating means.

The extension 24I, Figs. 14 and 15, has elongated slots 242 and 243, an interrupted bearing surface 244 and a rectangular groove 245. A member 246 having a tongue 241 is adjustably mounted on the surface 244 of the extension MI and held in adjusted position by means of screws 248 and 249 which pass through the slots 242 and 243.

The member 246 has side walls 256 and 25I having ways 252 and 253 respectively. A wall 254 encloses the right hand end of the member 246 while a vertical projection 255 partially encloses the left hand end of the said member. A screw threaded adjustable stop 256, mounted in the projection 255, is held in adjusted position by means of a check nut 251.

Slidably mounted in the ways 252 and 253, of the member 246, are ways 258 and 259 of a roll carrying member 260. Gibs 26I and 262 maintain the roll carrying member in assembled relation to the member 246.

A depending substantially hollow boss 263 on the member 260 forms a housing for a spring 264 one end of which abuts the end wall 254 of the member 246 and maintains the roll carrying member 266 in its normal or left hand position against the adjustable stop 256.

On the upper side of the roll carrying member 266 is a pair of bearings 265 and 266 in which is mounted a shaft 261. Rotatably mounted on the shaft 261 is an arm 266 which is held in the raised position shown in Fig. 14 by means of a coil spring 269 one end of said spring being attached to the arm 268 and the other end being attached to the bearing 265 whereby movement of the said arm 268 in a clockwise direction will be against the action of said spring. It is to be noted that the compression spring 264 exerts a greater power than the coil spring 269 for the purpose which will presently be explained.

In a pair of hubs 216 and 2H on the end of the arm 268 is mounted ashaft 212 on which is rotatably mounted a roll carrier 213 having a roller 214 of resilient material, on a stud 215. A rearwardly extending portion 216 has a latching surface 211, Fig. 16. The roll carrier 213 is maintained in its normal latched position by means of a compression spring 218 carried in a recess 219 in the end of the arm 268. The arm 268 has a rectangular groove 266' on the upper side thereof in which is fulcrumed a latch 26!] on a pin 26L The latch is held in locking position by means of a compression spring 282 which is supported in a recess 283 in the groove 280 of the arm 268, Figs. 14 and 16. Also in the groove 286' is a roller 284 rotatably mounted on a pin 285.

On the bracket 239 and above the roll carrying member 266 is a cylinder 286 having a piston 281 and piston rod 288, the end of said rod contacting the roller 284 carried by the arm 268. An extending arm 289, on the top of the cylinder 286, has an adjustable stop 296 which is held in adjusted position by means of a check nut 29I.

Below the bracket 239 and on the upright 3 is another bracket 292 on which is adjustably mounted a valve body 293 having a bore 294, Fig. 20, within which is slidably mounted a valve member 296 having an extension 291 extending through the end of said body. The end of the extension 261 is slotted and a rockable member 298 is mounted in said slot on a pin 299. At the end of the rockable member 298 is mounted a roller 366 on a stud 39! while depending from said members is a portion 362 to which is attached one end of a spring 363 while the other end of the said spring is attached to the extension 29'! whereby the action of the spring maintains the roller in its normal position as shown in Figs. 14 and 20. A pin 29l fitting in a key way 292", Fig. 20, prevents the turning of the extension 291 and thereby maintains the roll 30!! in correct relation to a cam 394.

The cam 364 is adjustablymounted on the wiper slide it! and is held in adjusted position by means of screws 399 and 386. The cam 394 can be mounted on the main slide it just as readily as on slide i8 but is shown on the latter by the way of illustration and not of limitation. Cam surfaces 39? and 388 in different planes are provided by the cam 399 for the purpose of actuating the valve member 298 through the roll 399. As shown in Fig. 14 the slide is in its uppermost position and is ready to descend but when the slide is ascending, the top of the cam 392 contacts with the roll 309 and rocks the member 298 about its fulcrum 299 so that the valve member is not moved longitudinally.

The valve member 293, Fig. 20, is provided with reduced portions 399; 318 and 3H and full sized portions 3E2, 3l3, 8M and 3l5. The valve body 293 is connected to the main valve 39 by means of a lead 356, out into the pipe 68, entering at port 3H so that fluid under pressure is always maintained in the valve body 293 whenever the main valve 39 is opened to pressure.

The valve body 293 also has exhaust ports 3l8 and 3E9 and ports 328 and 32! said last named ports being connected by pipes 322 and 323 to the right hand and left hand cylinders 288 and 286' respectively. A branch lead 324 is cut into pipe 323 and connects said pipe with a port 325 in the said valve body. As shown in Fig. 20 the valve 299 is in its normal position at which time the fluid under pressure entering a port 3H is held within the area provided by the reduced portion 3! 8 between the full size portions 3 I 3 and As'the slide l8 descends the cam 384 forces the valve member 293 to the left by means of the cam surface 381 at which time the full size portion 3l3 opens the recessed band 328 so that fluid under pressure will flow from the entrance port 3H to port 32I, pipe 323, and port 321 in the left hand cylinder 283, the area of the port being *adjustably restricted by means of a valve .328, Fig. 14. While the movement of the valve member 293 to the left opens up the port 32! to pressure it does not move far enough to allow fluid under pressure to enter port 329 as the full size portion 3M does not uncover the band 329 and neither is the by-pass exhaust port 325 uncovered. by the full size portion 3H2.

With fluid under pressure entering the rear end of the left hand cylinder 286 the piston 281 is caused to move to the right, Fig. 14. As the piston 28'! moves to the right the piston rod 288' rocks the arm 298 about its fulcrum 261 against the action of the spring 269 until the resilient roll 214 is in the position as'shown in Fig. 17 at which time a cam roll 339, mounted on a stud 33! on the arm 238, contacts a cam 332 mounted on the member 249.

When the strip or presser finger I23, Fig. 14, presses. the foil 333 on the bottleA the ends of the foil are forced downward so that as the roll .214 moves in an arc to the position shown in Fig.

17 the said foil will be partially wrapped around the bottle.

As the piston 28? continues to move to the right the arcuate motion of the roller 274 is controlled ,by-the shape of the cam 332 and therefore the l continued movement now causes the roll carrying member 260 to move to the right against the action of the spring 284 until the roll 274 reaches the position shown in Fig. 18 which is very nearly the end of the movement of the piston rod 288.

It is to be noted here that a depending portion 335 on the roll carrier 223 is almost in contact with a trip member 339 which is suitably fastened to the under side of the cam 332.

As the piston rod 288 reaches the end of its stroke the depending portion 335 abuts the trip member 336 and causes the roll carrier latch surface 2H to rock the latch 289 and release the roll carrier 213 so that it will assume the position shown in Fig. 19 which position it will maintain relative to the arm 288-until it is returned to the normal position shown in Figs. 14 and 16.

When the piston 298 reaches the end of its stroke the slide It? has moved downward so that the cam surface 388 is now in contact with the roll 389 and has moved the Valve member 296, Fig. 20, further to the left at which time the full size portion 3 I4 is moved far enough to open the'band 329 so that the full flow of fluid under pressure is admitted to port 329. From port 329' the fluid under pressure'flows through the pipe 322 to the right hand end of the cylinder 286' so that the resilient roll 224' goes through the same motions as described for roll 274.

Movement of the valve member 296 to the left as above outlined causes the full sized portion 3M to shut off the band 329 from communicating with the port 323 at the same time the full size portion 3 l 2 opens the exhaust port 325 and allows the fluid in the cylinder 286 to return to the sump by the way of port 3H3. As soon as'the port 325 is opened to exhaust the slide 268 starts moving to the left, Fig. 14, under the impulse of the spring 284, the rate of the return movement being controlled by adjustable valve 328.

When the cylinder 286 is opened to exhaust, the valve 326 maintains a volume of fluid which the spring 264 forces out of said cylinder. The force necessary to discharge the fluid through the valve 328 being great enough to maintain the cam roll 339 on the cam 332 until the slide 269 abuts the stop 256 at which time the spring 269 will raise the arm 268 to the position shown in Fig. 14 as the fluid continues to exhaust from the cylinder.

As the fluid becomes exhausted from the cylinder 286 the piston rod moves to the left and gradually allows the spring 269 to raise the arm 268 to the position shown in Fig. 14. As the said arm raises into its normal position the tail end of the latch 288 abuts the adjustable stop 298 which rocks the said latch enough to allow the spring 278 to return the roll carrier 273 from the position shown in Fig. 19 to that shown in Figs. 14 and 16 with the locking surface 21'! held by the latch 288.

The cam surface 388 holds the valve member 296 to the right long enough for the roll 224' to go through substantially the same motions as roll 274 went through in wrapping the left half of the foil around'the bottle. When the cam roll 388 reaches the end of the cam 364 a spring 331 in the valvechamber 294 forces the valve member 296 to the right shutting off the fluid under pressure from port 3!? and opening port 328 to exhaust port 318 whereby the fluid in the right hand cylinder can return to the sump. With the Valve 296 in the position shown in Fig. 20 both right and left hand cylinders are open to exhaust and the rolls in their normal position as shown in Fig. 14.

Mounted between the frame members 2 and 3, Figs. 1 and 2, is a container 338 in which a supply of adhesive is maintained. A supply roll 339 is mounted on a shaft 349 which is rotatably carried in bearings on the ends of the container. The shaft has a gear 34E mounted on one end. thereof. An arm 342 suitably fastened tothe upright 3 has a gear 343, which meshes with the gear 34I, and a sprocket 344. A belt or chain 345 gears the sprocket 344 with the sprocket 38, Fig. 2, whereby the supply roll 339 is rotated.

In operating this machine the operator places a bottle on the holder 10! and steps on the treadle 54 to move the main valve 39 to the position as shown in Fig. 20. As long as the operator maintains the treadle depressed the machine will go through its cycle over and over again but the instant he takes-his foot off of the treadle 54 the spring 56 will move the valve member 40 to the right, Fig. 20, thereby cutting off the supply port 345 with the full size portion 346, of the valve member 40, and stopping the flow of fluid from the pump to the rest of the system.

Referring now to Fig. 21 it will be noted that the supply port 345 intercepts the valve chamber 341 which is also intercepted by cross passages 348 and 349. The last named passages lead into chambers 35B and 35! which have outlet ports 352 and 353 respectively. The outlet port 352 being connected to the reverse valve I15 by means of the pipe I while the port 353 is connected to the reverse valve 57 by means of the pipe 68.

Within the chambers 350 and 35I are adjustable throttle valves 354 and 355 whereby the rate of movement of the various mechanisms can be readily adjusted to suit the prevailing conditions.

With the treadle 54 depressed and the valve 39 connecting the system directly with the pump, the fluid under pressure will flow out of port 353 to pipe 68 and reverse valve 51 which, as the slides I0 and I8 are in their starting or lower position, is in the position shown in Fig. 20. The fluid under pressure enters the reverse valve 51 at port 355 and passes around a reduced portion 351 of the piston valve 65 and out of port 358. The port 355 is connected by the pipe 69 to port 359 in the bottom of cylinder I3 at which time the slides II) and I8 start to move upwardly as a unit due to the fact that they are held together by means of the latch E5.

The said slides move upward until the wiper finger arms 83 and 84 are oscillated to a vertical position by means of the cam rollers 39 and 99 contacting with the cams 99 and Mill. When the wiper fingers 8i and 88 are closed over the bottle A they are in the dotted line position shown in Fig. 1. Just as the fingers close over the bottle the latch I5 is rocked by the cam 8| and releases the wiper slide I8 so that it starts its return or downward movement against the action of the dash pot 2| before the main slide I3 reaches the limit of its upward movement.

During the descent of the wiper slide I 8 the resilient wipers ill and 88 pass over the label or labels and firmly aflixes it or them to the bottle. As the said wiper slide nears the end of its descending stroke, the wiper finger arms 83 and 84 are again oscillated to open them to the full line position of Fig. 1 by means of the cam rollers 89 and 90 and cams 9i and 98.

At the start of the upward movement of the slide I0 a label or labels is or are reposing on the picker fingers I3 and T4 and the strip or presser finger I23 is holding the said label or labels on the bottle. When the slide I0 starts upwardly the label is stripped from the said picker fingers by the said strip finger.

As above noted the strip or presser finger I23 is pressed firmly against a bottle when the slides are in their lowermost position. As the presser finger arm I I1 is latched to the base I there is no movement to the presser finger until after the wiper slide I8 has caused the wipers 8'! and 88 to pass over the label and affix it to the bottle. As soon as the wipers have performed their function the stop member I4I, on the main slide I0, contacts with the latch I31 and releases the presser arm I ll so that it moves vertically upward due to the action of the spring II2 on the slide III! which carries the said arm II'i.

As the wiper slide I8 descends the cam 304 on said slide causes the actuation of the valve member 295, through the extension 291 and cam roller 33E], thereby causing the left hand foil roll 274 to start through its cycle and then the right hand foil roll 214 to start through its cycle so that during the descent of the wiper slide I8 the foil 333 is wiped around the end of the bottle at the same time that the body and neck labels are wiped in place.

The main slide I0 continues upward until the end portion I86 of the actuating member I80 contacts with the shifting lever I18 and causes the valve plunger I84 to be moved. Movement of the valve plunger I34 allows fluid under pressure from the main valve 39 to enter the upper end of the cylinder I14 and thereby cause the piston rod ill to move downwardly and rock the arm I6I in an anti-clockwise direction. Movement of the said arrrr causes the transfer roll slide I56 to move to the left and as the main slide I!) has reached the top of its stroke the picker fingers i3 and I4 are in the dotted line position shown in Fig. 2. As the transfer roll slide I53 moves to the left the resilient transfer roll 2I4 deposits a film of adhesive to the said picker fingers.

Just after the transfer roll 2 I 4 leaves the picker fingers I3 and I4 the cam 2I5 on the upper side of said slide I55 allows the label receptacle 225 to move downwardly and deposit a label or labels on said picker fingers.

Actuation of the valve plunger I84 as above pointed out also directs fluid under pressure to the right hand end of the cylinder I45, Fig. 2, which causes the piston rod I47 to be moved to the left. Upon movement of the said piston rod to the left the presser finger arm I ll, which has moved the fingers H23 vertically away from the bottle as above noted, is oscillated in an anticlockwise direction just prior to the descent of the label receptacle 225.

As the transfer roll slide I56 continues to the left a cam 369, Fig. 2, on said slide contacts with and depresses a rod 36L guided in brackets 362 and 363 fastened to the upright 3, against the action of a spring 354. One end of the said spring abuts the bracket 363 and the other end abuts a collar 365 fastened to the rod 35L A second collar 356 is fastened to the rod 36H below the bracket 363 to hold the said rod in position and maintain the proper spring tension on the spring 364.

The lower end of the rod 35! abuts the member 5I so that when the said rod is depressed by the cam 355 the member 51 is rocked about its fulcrum and shifts the reverse valve 57 and cuts oif the fluid under pressure from the main valve 39 and opens the main slide cylinder I3 to exhaust bythe way of port 367 in the reverse valve 57. The rate of descent of the main slide is controlled bymeans of a needle valve 368, Fig. 20, in the exhaust port 367.

The transfer roll slide i55 continues its movement to the left until the transfer roll 2M abuts theconstantly rotating supply roll 339 and receives a fresh supply of adhesive. The position of the transfer roll 2! in relation to the supply roll 339 is governed by the adjustment of the member lid on the piston rod ill whereby the desired. degree of contact between the said rolls is maintained. Just about the time that the said transfer roll and supply roll come in contact with each other the inclined portion i8! of the actuating member 30, on the descending slide Iii, contacts the arm N9 of the lever H8 and rocks it in a clockwise direction. moves the reverse valve member We to the position shown in Fig. 20 at which time fiuid under pressure enters the left hand end of thepresser armcylinder I 18 and the lower end of the transfer roll slide cylinder Ht whereupon the transfer rollslide I56 moves to the right, Fig. 2, and the cam 2I5on said slide moves the label receptacle 225 vertically upward in time to allow the now advancing strip or presser finger arm ill to position the presser fingers directly over the bottle.

The presser finger arm Ill is now in a substantially vertical position and the abutment member- M3 on the descending slide contacts with the stud M4 on the arm Ill and moves thesaid arm and its slide iilfi'vertically downward against the action of the spring H2 until the projection ilii'on the arm H! passes below the latching arm MB of the latch member 535. When As the main slide Ill continues its downward movement the wiper slide latch liisnaps into the slot 88 of the wiper slide and locks the two slides I 0 and 48 together at the same time the abutment member l9 rocks the member 68 and shifts the reverse valve 51 to the position as shown in Fig. 20 whereupon the above cycle is repeated unless the operator removes his foot from the treadle 54. in which case the spring 56 will move the valve member 46 and block off the entrance port 345 so that the'fiuid under pressurefrom the pump'will be out off from the hydraulic units of the machine and will escape through a relief valve 359 in the pressure line.

From the above description it will be seen that a machine requiring the minimum number of wearing parts with the maximum efficiency has been produced whereby it is possible to label bottles semi-automatically so long as the operator maintains the foot on the treadle.

It is also notable that the machinestops automatically as soon as the operator leaves it thereby stopping a waste of labels which would be continuously deposited on the picker fingers at each cycle of the machine were the machine to be left running.

Another notable feature of this machine is that the various mechanisms are interlocked so as to.

be interdependent as. to their several functions whereby a smooth running and extremely accurate cycle of operation is possible.

A further notable feature of this machine is that by using fluid under pressure-as the-motive Rocking the lever I18 power for .thevarious units a very'quietrunning machine is. produced.
